Welcome to the LWN.net Weekly Edition for May 7, 2026

• LLM-driven security reports disrupt coordinated disclosure: well-orchestrated disclosure of security vulnerabilities may be a thing of the past.
• Restartable sequences, TCMalloc, and Hyrum's Law: Linus decrees regression rules apply, even when a program violates the documented ABI.
• Bug-monitoring expectations and Fedora GNOME packages: FESCo requires tweaks to an automatic response saying GNOME bug reports are not actively monitored.
• Version-controlled databases using Prolly trees: a look at a B-tree variant used to support efficient version control for databases.
• Hardware-assisted Arm VMs for s390: work to enable Arm VMs on s390 may lead to better testing, debugging, and documentation of both architectures.

This week's edition also includes these inner pages:

• Brief items: Brief news items from throughout the community.
• Announcements: Newsletters, conferences, security updates, patches, and more.

Please enjoy this week's edition, and, as always, thank you for supporting LWN.net.
